🧲 fMRI is the most widely used method for studying brain activity during tasks.
📸 During an fMRI scan, pictures are taken of slices through the brain to measure neural activity.
💡 The brightness of each image in an fMRI scan indicates the level of neural activity in that area of the brain.
🧠 fMRI brain scanning measures changes in blood flow to active brain regions.
📷 fMRI creates a series of 2D pictures by taking slices of the brain.
🔊 During fMRI scanning, radio frequency magnetic pulses are used to reorient hydrogen atoms in the brain.
🧠 fMRI brain scanning measures the speed at which oxygenated hemoglobin returns to its original state in the brain.
⚡️ The scanning process involves manipulating hydrogen atoms using magnetic and electric fields.
⚠️ There is no significant harm or pain involved in the scanning procedure.
🧠 fMRI brain scanning is a safe method that has been used for decades with no evidence of harm to animals or humans.
🔬 Animal safety studies have shown that animals can be raised and scanned without any issues, including pregnant animals and their pups.
⏱️ The speaker, who has spent hundreds of hours in an fMRI scanner, has not noticed any negative effects, providing additional reassurance of its safety.
